Proximate Composition, Nutritionally Valuable Minerals, Protein Functional Properties and Anti-Nutrient Contents of Mucuna Preta, Mucuna Ghana and Mucuna Veracruz Mottle

Abstract

Results of the proximate composition, functional properties and physico chemical properties of mucuna ghana, mucuna preta and mucuna Veracruz mottle is reported. The ranges are; ash (3.17-4.33), moisture (8.50-8.85), crude protein (30.92-33.25) and crude fat (46.20-49.34). Mineral contents showed phosphorus to be most abundant while manganese and copper were least. Lead was not detected. Functional properties of the protein showed a good Water Absorption Capacity (WAC) ranges (145-160) and Oil Absorption Capacity (OAC) ranges (130.10-138.23). The foaming capacity (17.00-25.00), mucuna preta was least and mcuna ghana highest. The Oil Absorption Capacity (OAC) (130.10-138.23) with mucuna ghana highest and mucuna veracruz mottle least. The Least Gelation Concentration (LGC) and emulsion capacity (ES) are relatively good. The Foaming Capacity (FC) after 2 h showed appreciable and acceptable values (17.00-25.00) in which mucuna preta was least and mucuna ghana was highest. The Foaming Stability (FS) values were also within acceptable ranges (9.0-12.50). Emulsion stability (59.00-66.00) has mucuna ghana least and mucuna veracruz mottle highest. Plots of the protein solubility against pH showed protein to be soluble at both acidic and alkaline regions. Anti-nutrients in the samples showed tannic acid range (8.54-10.30), Oxalate mg/g (6.78-8.31) and phytate mg/g (55.11-85.47). The ranges were however within acceptable values.
